Mars decrypt virus

Yesterday I have been attacted from a virus called " MARS DECRYPT"
From that time I can nt oppen any of my files in my WD MIRROR DISC
They ask me to give them 500 $ in bitcoins in order to give me the key for the dectyption.
Do any one has an idea how I can solve my serious problem
Thank you in advance

This also happened to me. All files on my WDMyCloud device were rewritten as .pdf.mars files on Feb 2nd, and a ransom note demanding 300 Bitcoin was added.

Did you pay the bit coin?

No-- I can’t pay that.
